SLC22A7 and melanoma: Metabolism serves a key role in melanoma therapy escape as well as metastasis (8, 9), and we have shown that melanoma cells take up lipids through age-related expression of the SLC27A2 solute carrier family 27 member 2 also known as fatty acid transporter FATP2 in response to ceramides produced by aged fibroblasts, which are then utilized to escape therapy (5).
